Phantom Fungus

This creature looks like a brown and greenish-brown mass with a cluster of nodules atop the main mass, though it is visible only when dead. A cluster of nodules atop the main mass serve as sensory organs. The creature feeds and attacks with a gaping maw lined with rows of teeth. Four stumpy legs support the creature and allow it to move about. This ambulatory fungus is naturally invisible, making it a feared predator among subterranean inhabitants.
